Application filed May 31, 1919. Serial No. 300,838.

-' tion.

' The present invention is directed to improvements in detachable heels, and is an improvement on my Patent No. 1,301,4t03, issued April 22,1919. I

The primary object of the, invention 1s to provide a shoe heel, preferably of rubber, which may be easily and quickly attached to or removed from the-heel of thesole with the aid of a small pointed instrument. p

'A further object of the invention is to provide a heel of this nature having the neatappearance of a permanently attached heel, but at the same time being capable of quick detachment, whereby heels constructed in accordance with my invention may be readily interchanged.

Another object of the invention is to provide extremely simple and durable means for detachably securing the heel to the sole without the aid of nails and services of a shoemaker. r

Still another object of the invention is to provide resilient means for interlocking the heel to the heel portion of the sole, saidmeans having associated therewith means to prevent, ingress of foreign matter to the interlocking means,

A still further object ofthe. invention is to provide novel means-for reinforcing the plate carried by the sole, whereby the same will be braced at the point where the spring carried by the heel exerts themost strain.

An embodiment of the invention that is at present considered the preferable one, is illustrated in the accompanying drawing, wherein Figure 1 is a fragmentary side elevation of a shoe equipped with the heel.

Referring to the drawing, 1 designatesa shoe, and 2 the detachable heel, which is formed from rubber, but it will be of course understood that any other material suitable for the purpose may be used. I

The sole plate 3 is substantially U-shaped in outline, the side arms thereof being connected at their forward ends by an integral bar 4:, which prevents spreading of the arms." The plate 3 is provided with a marginal right angle flange 5 which terminates in an angularly disposed flange 6, said flange forming in conjunction with the plate a.

groove 7, the purpose of which will appear later. The plate 3 is attached to the heel portionof the sole of the shoe 1 in any well known manner.

Mounted on the bar 4 is a pair of stops 8, I

each of which consists of a ,hori'zontal flange 9 and angularly disposed vertical webs 10 and 11, the webs 11 of the stops being spaced, as clearly shown in Fig." 2 of the drawing. The flanges 9 are riveted or otherwise suitably secured to the bar 4. The forward edge of the bar 1 is formed with a pair of spaced tongues 12, which are bent downwardly and flush against the webs 11 of the stops 8, thus firmly bracing the same;

The plate 13, which is adapted to be at tached permanently to the rubber heel 2 is U-shaped, and the arms 1% of which have their forward ends formed with inwardly di-' rected tongues 15, the inner ends being spaced to accommodate the forward end of the leaf spring 16. .The rear end ofthe wardly inclined flange 17 adapted to slidably engage the groove 7 of the sole plate 3, and since both of the plates are U-shaped it is obvious that when engaged they will fit snugly. a

The arms 14, as well as the tongues 15 and bight portion of the plate 13 have secured thereto the upper ends of the posts 18, the enlarged heads 19 thereof being embedded in the rubber heel 2, whereby the plate 13 is firmly secured to the heel. It is obvious that any material capable of being molded may be used for the heel, and will effectively remain engaged with the plate through the medium of the posts 18. v

The forward end of the spring 16 is formed with a downwardly directed lip 20, which is adapted to move in the pocket 21 formed in the heel 2 as the spring is flexed upwardly and downwardly. The forward end of this spring engages the rear faces of g the webs 11 of the stops 8 when the sole and heel plates 3 and 13, respectively, are engaged, thus preventing accidental disengagement thereof. .VVhen these plates are in their operative relation the lip 20 of the spring 16 will be flush with the inner faces of the webs 11,-thereby closing the space between said webs and bracing tongues 12 to vent ingress of foreign matter. Should foreign matter enter between the sole plate and heel plate the spring 16 would become clogged, and lose its effectiveness, as would the groove 7.

To attach the heel 2 to the sole portion of the shoe 1 it is only necessary to place the same so the flange 17 of the plate 13 will enter the groove 7 of the plate 3. The heel 2 is then slid rearwardly, and at which time the spring 16 is depressed until the stops 8 ride off of the forward end thereof, whereupon the spring expands and the forward end thereof snaps in behind the webs 11 of the stops 8, thus firmly interlocking the plates 3 and 13, and thus the heel 2 to the shoe 1.

Since a small pointed instrument can pass between the tongues 12 and webs 11 of the stopsthe forward end of the spring 16 can be engaged and depressed until it clears the stops, whereupon the heel 2 and its associatpreed plate can be removed from engagement with the sole plate 3.

Thus it will be seen that a heel has been provided which can be easily and quickly attached or detached, and when once in place can not be accidentally displaced.

What is claimed is: 1. A detachable heel comprising, in combination, a plate secured to the heel portion of the shoe sole, and having stops carried thereby, a heel having a plate carried thereby, a spring fixed to said'plate for engaging one side of the stops, and tongues associated with the first named plate and bearing against the opposite side of the stops.

- 2. A detachable heel comprising, in combination, a plate secured to the heel portion of the sole, stops carried by the plate, the heel having a plate carried thereby, and means associated with the last named plate for yieldably engaging one side of the stops,

and tongues associated with the first named plate, and bearing against thevopposite side 7 V V I of stops. I

3. A detachable heel comprising, in combination, a plate for attachment to the heel portion of a sole, spaced stops associated with the plate, the heel having a plate secured thereto, interlockingv means carried respectively by said plates, and means for closing the space between the stops associated with the interlocking means.

4:. A detachable heel, comprising in combination, a plate for attachment to the heel portion of thesole, and having a marginal groove, the heel having a plate connected thereto, said plate having a flange for slidably engaging said groove, spaced stops associated with said plate, a spring having one end fixed to said plate, and a lip carried by the free end of the spring, said lip serv ing to close the space between thestops when the free end of the spring is engaged therewith. r I

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. V ALFRED V. DES MOINEAUX.
